To assess the efficacy and safety of a soft acrylic intraocular lens (IOL) in small incision cataract surgery.
Sixty-four eyes of 64 patients (mean age 71.0 +/- 7.7 [SD] years) who had phacoemulsification and implantation of a soft acrylic IOL were followed for 2 years.
At day 1, 96.9% of patients had corrected visual acuity of 20/40 or better, and 50.0% had 20/20 or better. At 2 years postoperatively, 100% had 20/40 or better, and 86.3% had 20/20. Surgically induced keratometric cylinder remained quite stable throughout the 2 year follow-up period, with axis-based astigmatism of +/- 0.3 diopters. Flare intensity measured with the laser flare-cell meter was less than that with other type of IOLs measured, including poly(methyl methacrylate) and silicone. Neodymium:YAG laser capsulotomy was performed in seven cases (11.1%). without causing damage to the optic. No other postoperative complications were encountered.
Soft acrylic IOLs have clinically apparent advantages in small incision cataract surgery.
评估软性丙烯酸人工晶状体（IOL）在小切口白内障手术中的有效性和安全性。
对64例患者（平均年龄71.0±7.7[标准差]岁）的64只眼睛进行了超声乳化白内障吸除术并植入软性丙烯酸IOL，随访2年。
术后第1天，96.9%的患者矫正视力达到20/40或更好，50.0%的患者达到20/20或更好。术后2年，100%的患者矫正视力达到20/40或更好，86.3%的患者达到20/20。在整个2年随访期间，手术诱导的角膜散光相当稳定，基于轴的散光为±0.3屈光度。用激光散射细胞仪测量的眩光强度低于包括聚甲基丙烯酸甲酯和硅酮在内的其他类型IOL的测量值。7例（11.1%）患者进行了钕：钇铝石榴石激光晶状体后囊切开术，未对视光学部造成损伤。未遇到其他术后并发症。
软性丙烯酸IOL在小切口白内障手术中具有明显的临床优势。
